摘要

"Economizer of concrete for the construction of ribbed floor slabs with massive appearance.The application refers to a certificate of added invention of the IP 9900077 - 6 deposited on 06 / 01 / 1999, for the protection of development introduced into the object of the invention.Characterized by presenting new provision constructive in fu00f3rmas (f) for the construction of ribbed floor slabs, as well as, new techniques of assembling in the construction process.The fu00f3rma (f) is composed of four equal parts, which are made of recycled material, through the process of the air injection in mold industry.And these parts are provided with tenons (6 and 7), male and female) respectively, which enable the unification of the parties in a single block.This model fu00f3rma (f) is more resistant than the initial one; it enables the use of smaller modules for the realization of finishes in the construction, and.Allows fitting of electro pipelines and / or other pipes on the rails (1) it developed, and may be distributed in the senses of longitudinal, transverse and diagonal slab.In addition to the new provision constructive fu00f3rmas here requested, it should be pointed out that the construction process also has the addition and / or replacement of assembly techniques.Including the development of a pin (3) lock fixing the boxes in the madeirite (4) in order to prevent the fu00f3rmas (f) rise during concreting.
